I'm going to run you through how to white set a rendered wall.
White setting a rendered wall will give it a nice smooth finish, it'll come out with
a nice glossy glass look by the end of it.
I have my materials which is a lime putty and I also have a hardwall plaster, I've got
my drill, my tub, a bucket of water and my hand tools which is my hook and trowel a scoot
and a paint brush, and of course my safety gear.
I'm going to start off by pouring my putty into my drum.
The hardwall powder is sort of like a core for the putty.
It will still come out as a putty once you mix it through.
The hardwall just gives it an extra bonding between the render and the white set.
I'm now going to mix up a consistency of one bag of putty mixed with half a bag of hardwall.
When you're mixing up the putty, you want to get it to a nice thick consistency.
It's almost like baking a cake, so just get that nice creamy feel to it and you'll be
ready to go.
You might need to add a little extra hardwall, maybe add a little bit water.
Just give it a play till it feels right for you.
Using my trowel, I now scrap off all the excess that sort of clung to the sides, that way
you can remix all those little extra bits in.
Before applying your white set to your render, you would like to put some moisture on it
just to help with the adhesion between both products.
As you can see the difference in color where there is some water and where it's just pure
dry with no water.
You want it to be more like that.
If you've got access to a hose, this process will go a lot smoother and faster.
I'm going to get it wet with my spraying mist.
I'm now going to apply the white set to the wall.
I'm going to start left to right and go from the bottom to the top.
Using your nice, clean, fresh trowel as well to apply this, I'm going to be going in a
sort of an arched motion, pushing away and then coming back with the opposite side of
my trowel.
You can do it in a one coat or a two coat process, I prefer a two coat.
We're doing...The first is a very fine, thin scratch coat, that way I fill in any holes
and imperfections that way it doesn't sag in the drying process.
As you can see my first scratch coat, you do see a few gray spots here where the background
is showing through then with your second coat you'll see the difference in how purely white
it can be.
Now just finished the bottom half of my wall and that way I'll be ready to trowel.
If you still got a few gray spots showing through, it might be a tad wet.
So what you can do is just put a bit of fat on that and let it harden up a bit.
That way when you come back to trowel on it, you should have a bit more extra thickness
there to peel on.
I have put it on a little bit thicker because as I do my two to three trowel overs, I will
be taking off millimeters at a time to get it back to a smooth finish.
You still want to keep a nice white color.
There is some important factors in the trowel technique.
If I do tilt my trowel too much, I can take a bit too much off as we'll see now.
If we put too much of an angle and apply pressure, I could take back all the way to that.
The good thing is I'll get some fat on it so I can apply that flat and that should put
the fat back onto the wall.
And now I can trowel it and smooth it off again.
Now I've finished applying my second coat.
I will have to let it dry for a little bit now.
If I touch it like that, you can see I'm still leaving finger marks, that's probably still
a bit too wet.
I'll take this time now to clean out my tools, clean out the left over of my putty and I'll
come back and see how it's going.
My next step is the first trowel process.
Using a paint brush, I'll be flicking some water up, I'll be troweling up my wall that
way I'll be taking out any fat excess and I'll be filling in any cracks and any gaps.
And then I'll leave it to dry and then I'll begin my second trowel process.
The troweling process is pretty much the same each time.
I will do it two to three times but just it's because the wall will continue to go hard.
You know to keep that pressure on it and smooth it out each time.
Now I've done my three trowel process.
My wall is finally finished.
I will not leave it a few days to dry before I seal or paint or do any extras on it.
